low-temperature-polymer-cell: 2700mAh -40℃ High-Rate Discharge Lithium Battery for Extreme Environments
Introduction
In extreme cold environments like Arctic expeditions, vaccine cold chain logistics, or high-altitude drone missions, ordinary batteries falter. Yet, the low-temperature-polymer-cell excels. This ultra-low-temperature polymer cell achieves 1C charge/discharge at -40℃, 92% capacity at -40℃ under 0.2C, and boasts a slim 9.2×68×40mm polymer structure. UL-certified and engineered for 300+ cycles at -20℃, it’s the definitive industrial freezing-resistant polymer cell for gear that can’t afford downtime in freezing conditions.

Why low-temperature-polymer-cell Dominates Extreme Cold Scenarios
1. -40℃ High-Rate Discharge
“1C Discharge at -40℃: This freezing-resistant polymer cell retains 80% capacity (2160mAh) — enough to power Arctic exploration drones for over 2 hours. Ordinary polymer cells shut down at -20℃, making them useless in polar missions.”“0.2C Ultra-Retention: Maintains 92% capacity (2484mAh) for 24+ hours of cold chain tracking — critical for vaccine transport integrity, where ultra-low-temperature polymer durability is non-negotiable.”
2. 18650 Compatibility + Polymer Design Flexibility
“Slim 9.2mm Build: Fits into curved surfaces like drone wings or wearable tech — offering the familiarity of 18650 form factors but with a 30% thinner profile than traditional cylindrical low-temperature-polymer-cell designs.”“1A Fast Charge: Refuels 2700mAh in just 1 hour — perfect for military night-vision gear or winter sports electronics that need rapid turnaround in -30℃ conditions.”
3. UL-Certified Safety
“UL 1973/1642 Compliance: No thermal runaway at -40℃ — safe for human-worn devices like heated vests and even explosive cold zones such as gas pipelines, where industrial freezing-resistant cell safety is paramount.”“0℃ Charging Capability: Operates in 0℃ cold storage environments — a feat ordinary polymer cells can’t match (they require 5℃ minimum), eliminating downtime in refrigerated logistics.”
Application Scenarios
1. Arctic & Military Operations
“Polar Research: low-temperature-polymer-cell powers ice-core drilling equipment and -40℃ drones — the 2700mAh capacity supports 12+ hours of uninterrupted data collection in polar darkness.”“Military Missions: 1A fast charging refuels night-vision goggles in 1 hour — ensuring readiness for -30℃ reconnaissance missions, backed by ultra-low-temperature polymer durability.”
2. Cold Chain & Refrigeration Logistics
“Vaccine Cold Chain Sensors: 92% capacity at -40℃ (0.2C) keeps trackers running 24+ hours — guaranteeing vaccine efficacy during global transport, with industrial freezing-resistant cell stability as the backbone.”“Refrigerated Truck Controllers: 1A discharge powers temperature management systems — recharges in 1 hour at 0℃, so low-temperature-polymer-cell-driven logistics never miss a delivery window.”
3. Outdoor & High-Altitude Equipment
“High-Altitude Drones: The 9.2mm low-temperature-polymer-cell fits seamlessly into wing structures — 2700mAh enables 4-hour flights at -20℃, capturing aerial data in mountainous regions.”“Winter Sports Tech: Powers smart ski goggles and heated base layers — 1-hour recharge between runs, with ultra-low-temperature polymer durability ensuring season-long performance.”
